Can moldy corn still be used?
In general, if the corn is found to be moldy, it can no longer be used as a feed. Long-term consumption of low-dose moldy corn in humans and animals, mycotoxins will deposit in the body, especially for livestock and poultry, mycotoxins will be enriched in the muscle tissue of livestock and poultry, endangering human health through the food chain.
However, some farmers feel that it is wasteful to throw, so is there any way to deal with it so that corn feed can be used within the safe range of mycotoxins?
1. Wash with water, grind the mildly moldy corn, pour it into a closed container, add four times of water, stir and soak in water, stir twice a day, wait until the water becomes colorless, theoretical basis It is a toxoplasmin toxin that is soluble in water.
2, degerming, the moldy corn is ground into 1.5-4.5mm granules, add five times the water, stir, simmer, when the embryo fragments of the corn float on the surface, remove the debris, repeated many times, you can play Reduce the effects of toxins. The corn germ is located in the lower part of the corn kernel, and the germ oil content is as high as 40%. If the corn germ is improperly stored, it will be contaminated by aflatoxin, zearalenone and vomiting toxin in a dark or humid environment with poor ventilation.
3, lime soaking method, the moldy corn is crushed into small particles of 1.5-5mm, the fine lime powder is infiltrated in a ratio of 0.8-1%, and then mixed with water in a ratio of 1 to 2 in the container, need to stir for one minute Then, let stand for 8 hours, and finally rinse with water to feed.
After the above methods, how to check whether the toxins meet the feed safety standards?
The latest "feed hygiene standards" on the mycotoxin limit mainly includes the following aspects:
In summary, for corn mold is not so serious, it is still possible to take measures to reduce the risk of mycotoxins, but usually still have to do a good job in corn procurement, mildew is too serious, it is absolutely impossible to feed cattle, so as not to Mycotoxins are poisoned, causing some damage.
Shanghai Fly Measurement Bio-Fluorescence Quantitative FPOCT Technology Platform Detection Principle
When the sample is added dropwise to the sample application zone, the analyte in the sample binds to the fluorescent microsphere-labeled antibody in the binding pad and is chromatographed forward by capillary action. When the detection zone is reached, the detection line is fixed on the T line. The antigen is bound to the remaining fluorescent microsphere-labeled antibody, and the amount of the labeled fluorescent microsphere-labeled antibody on the detection line T is inversely proportional to the amount of the analyte in the sample, and the quality control line C-line is combined with the fluorescent marker sample. Regardless of the amount of the analyte, other fluorescent labels continue to be chromatographed to reach the absorption zone. After the end of the chromatography, the fluorescence intensity of the T and C lines is read by a fluorescence reader and the T/C value is calculated. The content of the sample to be tested can be calculated by the standard curve built into the instrument.

Shanghai Fly Measurement Bio-Fluorescence Quantitative FPOCT Technology Platform Advantage
Based on the leading fluorescence quantitative FPOCT technology platform , Shanghai Festo Biotechnology has developed a rapid quantitative detection system for mycotoxin, including a mycotoxin rapid detector and a mycotoxin series of quantitative quantitative rapid test strips. The system combines colloidal gold with rapid enzymes. The combination of immunoassay and accurate chromatographic methods can quickly and accurately determine the mycotoxin in feed ingredients and feed products within 8 minutes, including aflatoxin B1, zearalenone, vomiting toxin, ochratoxin A, The content of fumonisin, T2 toxin, etc., the sample pretreatment is simple (only 7min), the six toxins can be extracted at one time, the operation is simple, only one step is needed, no standard is needed, no standard curve is needed, and fluorescence immunoassay is used. The analyzer readings are accurate and reliable, and can be printed on site. The accuracy is highly consistent with the HPLC method. It provides a new technical means for the rapid detection and control of mycotoxins. It is suitable for all kinds of feed processing enterprises and breeding enterprises. Third-party testing agencies and relevant government regulatory agencies.
Test sample application range
Feed sample preparation process
1, crushing;
2. Shock extraction (5min);
3. Stand still or centrifuge;
Highlights:
1 All samples can be tested for all kinds of mycotoxins in one extraction, which greatly reduces the workload of sample preparation and improves the detection efficiency. The entire pre-treatment process takes only 7 minutes.
    2 no need to adjust the pH value after extraction of any kind of sample;
Detection operation process
1. Dilution;
2. The incubation reaction was applied for 8 minutes;
3, reading, print test report;
Test result interpretation and output
Using mycotoxin fluorescence to determine the reading of the rapid detector, the test results are more accurate and objective, avoiding human error.
The test result will be presented on the liquid crystal display of the fluorescence reader. At the same time, the paper test report can be obtained by pressing the print button. In addition, after the WIFI data upload function of the instrument is turned on, the relevant data information will be automatically uploaded to the “Food Safety Traceability Managementâ€. Cloud platform for easy traceability and quality management.
